To all whom it may concern:

Be it known that I, GEORGE C. RICHARDS,

a citizen of the United States, residing at Berkeley, in the county of Alameda and State of California, have invented new and useful Improvements in Fume-Condensers, of which the following is a specification.

This invention relates to a fume condenser.

One of the objects of the present inven tion is to provide a simple, cheaply manufactured, easily operated, efficient fume (3011'? denser adapted to be used in connection with smelters, retorts, garbage burners and furnaces in general when certain ores or materials are handled and where escaping fumes or smoke are objectionable both from a sanitary and economical point of view. Another object of the invention is to provide a fume condenser which may be di rectly connected with thelescape fiue of a smelter or like device,-and in which all escaping fumes or gases are subjected to a water spray action and contact with a series of'water sprayed fabric surfaces to promote condensation. Further objects will hereinafter appear. j

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having referenceto the accompanying drawings, in which ;.Figure 1 is a central, vertical, longitudiit connected with a blower and a furnace.

Fig. 2 is aplan view of the condenser. Referring to the drawings indetail, A indicates a standard form of furnace which may be used for reducing cinnabar, zinc, antimony or like ores, or which might be employed for burning garbage or other material. '2 indicates the main escape flue connecting with the furnace chamber; 3 a blower; and B the condenser in general. Any suitable form of suction blower may be employed and this, together with the flue connecting tube 4, is preferably water-j acketed to maintain the temperature as low as possible.

The fume condenser proper consists of a box-like structure comprising a bottom section 5, sides 6 and ends 7. The box is pref- Specification bf Letters Patent. P t t J l 16, 1918 Application filed April 30,

erably narrow and long, as shown, and is otherwise provided with a plurality of downwardly extending baflie plates 8. Formed on the lower and upper end of each baffle plate is a seat projection 9 for the reception of a frame 10 carrying a canvas fabric 11. The. baflle plates extend approximately half way down into the box and each canvas supporting frame 11, therefore, assumes an inclined position P approximately such as shown. I

Extending longitudinally of the box, above the canvas frames and the battle plates 8, 1s a series of spray pipes 12 to which water is delivered from a circulating pump Also connected with, the pump, through pipes 14 and 15, is a pair of spray nozzles 16- and 17 the nozzle 16 being capable of pro ecting a cone-like jet and being preferably posltioned in the discharge end of the blower, .while the: nozzle 17 is preferably designed to discharge a fiat or sheet-like spray just ahead of the discharge pipe 18 which enters the box-like chamber of the fume condenser. The condenser is otherwise provided with an overflow pipe 19 which connects with a sump 20, where the water is permitted to cool and the denser particles are permitted to settle and the suction side of the pump may be directlyconnectedwith the sump by a pipe 21 to re-ciroulate the .water, if desired.

In actual operation, with the blower revolving, it can readily be seen that a sulficient suction is obtained to draw all the fumes, smoke and gases from the furnace through the flue 2 and the blower casing 3 and dischargethe same through the pipe 18 directly into the box-like chamber of the condenser. The gases in discharging from the blower are first subjected to the spray action of the nozzle 16 and then to the spray action of the nozzle 17 The sheet-like spray here produced serves as a secondary condenser and at the same time deflects the discharging gases in a downward direction, thereby preventing the major portion of the gases from striking the first fabric surface. The pump 13 being operated at the same time produces suflicient pressure to operate the nozzles 16 and 17 and also delivers a 11. They fumes, can only escape from: the,

box-like chamber by passing through the fabric surfaces and as theyareherebrbught into intimate contactavitli the vater satirrated fabric and the Water spray exerted,

against same, they will immediately conens -midtliere dhere to th ric; i ri aee or fall back'into the bottom of the condenser Where they are Washed ont by the ,discharg; ing Water and finally delivered through the pipTel9 into the sump 20, Where they are per:

mitted 1 to, settle. and are: finally removed,

when desired.

.1111 actual: practicenit has. been found: that comparatively. small: quantities of condens: able) matten adheres to the canvas or fabric surfaces. as th ese; areialw-aysisubzj ectedi to the Water spray discharging from thelpipes l2. Thisspray act-ion removes the condensed ma; terialbeforeit can build. up-tosuch an ex,- tent as to clog'the several surfacesprovided and they are, therefore,retainedacleaniand opengtolpermitl the airto freely. discharge from the condenser, thus preventing the for mation of pressure Within. the condenser or back pressure on the blower.

A condenser constructed as, here vshow-n, employedv in; connection with, a. smelter handlingsulfidores, was foundlto. be so efficient in actionthat; itivas impossible to! detect ,any sulfur odorvor traces of same when analyz ing the discharging, air; passing through the water.sprayed-canvassurfaces. It has also been found; to. bevel-y eflicient when employed 1 in connection With cinnabar furnaces as the large condensing surfaces provided immediately.v precipitate the quicksilver and permit it to -.settle inthe, bottom of the box.- like chamber, Where. it can. be easily.v removed on continuously.- permitted; to v discharge through the pipe 19. i

While two specific uses are, here. described, I:- Wi sl1= it. understood: that. it can be equally efiiciently. employed in icomiectionnwith garbage burners and'other; forms-,offurnaces; and that; While, the; canvas. surfaces o are here shown, as. inclined; it. is obv-iouslthat they maybe positionedeither horizontally or vertically, and: that two or moresupenposed layers may. be employed; if desired.=

v Thematerials ands-finish of the several parts of; the fume, condensermay otherwise besuchi as. the experienceand judgmentv of the manufacturer may. dictate.

I Wish it, understood that variouschanges in. form, proportions and minor details of construction may; be resorted-1130, Within the scope. .of: the/appended: claim and; that 1 I: do not-wish to. limitgmyself; to, the specificxlesign and construction. here shown.
